Handkey fingerprint reader lets in authorized, keeps out riffraff

Federal Bureau of Prisons sites have used biometrics such as those in HandKey from
Recognition Systems Inc. of Campbell, Calif., to control personnel movement.

But biometrics is playing an increasing role in network security—either in lieu of
or in addition to passwords to verify user identity as part of a logon; or in physical
security of network facilities.

The device stores fingerprints in a database and assigns entry rights.

If a user wanted to enter a server room, for example, he would put his hand into the
device and press against levers on a plate.
